GPS Capability
The M330G includes a GPS receiver and an easy to install external GPS puck antenna for better accuracy and performance. The small compact GPS puck antenna provides your location, bearing and speed by using information from GPS, GLONASS and SBAS. This information is used for DSC (Digital Selective Calling) calls. Hook up the GPS puck antenna for the most accurate GPS and DSC functionality to work.
Compact and Easy to Use
The M330’s small size makes it easy to install into vessels with limited space. The dot-matrix display is clear and easy to read. A combination of the directional keypad and soft keys provides simple, smooth operation. Most used functions are assigned to soft keys for quick one push function access.
Additional Features
- AquaQuake™ draining function
- Built-in Class D DSC with a CH70 dedicated receiver
- Common NMEA interface for external GPS/NAV connection
- Tag scan and favorite channel functions
- Dual/tri-watch function for monitoring CH16 and/or call channel

Icom’s M400BB is perfect for boats that need a radio but don’t have room on the helm. The M400BB consist of a two-piece, black box configuration. Install the full RF black box unit in an out-of-sight place and connect the COMMANDMICIV™, HM-195 to the cockpit or fly bridge. The HM-195 allows operation of all radio functions including DSC, radio and hailer horn. HM-195 also utilizes the same user soft key interface used on Icom’s latest range of marine radios for easy operation.

Active Noise Cancelling
The built-in bidirectional active noise cancelling reduces background noise to up to 90% and improves both your transmitted voice and incoming call. Hear and be heard more clearly.
10W Amplifier
The M400BB has a built-in 10W amplifier that increases the audio output from an additional external speaker. The public address function allows you to make an announcement from the microphone like a loud speaker.
NMEA Interface
When connected to an external GPS receiver, current position and time are shown on the COMMANDMIC™ display. When receiving DSC information from another vessel, the radio can transfer it to a navigational device via NMEA 0183 connectivity.
Additional Features
- AquaQuake™ water draining function
- Dual/tri-watch function for monitoring Ch.16 and/or call channel
- Priority and normal scan
- Class D DSC
- Connect to the optional MA-500TR and the AIS target call function allows you to set up an individual DSC all from the MA-500TR.
